Back in May, Alden Ehrenreich was officially tapped to play young Han Solo in a stand-alone film within the larger Star Wars franchise. It's a role that plenty of young Hollywood stars were shooting for, and one that ultimately went to a mostly unknown actor whose credits include small roles in Hail, Caesar!, Blue Jasmine, and Stoker.

The team behind the upcoming Star Wars films (Rian Johnson, Phil Lord and Chris Miller, and LucasFilm president Kathleen Kennedy) appeared this weekend at the Star Wars Celebration Europe at the ExCel Centre in London last week and officially introduced Ehrenreich to a crowd of thousands.

One can only imagine—which is what Conan did on Friday night, gathering a few of the A-list actors who "auditioned" for the role. It's a diverse group that includes Bill Hader, Thomas Middleditch, Will Arnett, Adam Sandler, and Jeff Goldblum. (Conan was open to testing non-white guys, too: Melissa McCarthy, Jodie Foster, Kumail Nanjiani, and 50 Cent also gave it a shot.)

It is admittedly funny, although bears a little resemblance to this 1997 SNL sketch in which '70s era A-listers (such as Christopher Walken as played by Kevin Spacey and Richard Dreyfuss as portrayed by Darrell Hammond) also did screen tests for the original Star Wars.

The '97 sketch was so great, of course, that SNL couldn't help but retool it with modern day celebrities (Cecily Strong as Sofia Vergara, Emma Stone as Emma Stone) auditioning for Star Wars: The Force Awakens.
